Welcome to the Friends of Stocker's Lake Website

This website is owned and maintained by Friends of Stocker’s Lake (FoSL), a registered charity. FoSL exists to :

  1. - conserve, safeguard and enhance Stocker's Lake as a Local Nature Reserve
  2. - help and extend the scope of the work of the warden at Stocker's Lake
  3. - foster public support for and appreciation of Stocker's Lake as a local nature reserve.

Stocker's Lake, near Rickmansworth just inside the M25, is bordered on one side by the river Colne and on the other by the Grand Union canal. It is a place of great beauty and it supports a huge variety of wildlife, especially birds, particularly winter wildfowl. It is owned by Affinity Water and managed by Herts & Middlesex Wildlife Trust, actively supported by local people who are the Friends of Stocker’s Lake.

Within this website you will find details of organised walks and other events on the reserve, news of interesting recent sightings of birds, details of how to join FoSL for a mere £5 per year, and much more.

All events ...


Herons breed early in the year and their 2021 nesting efforts are already well underway at the lake. A great video clip was recently captured by one of our offshore cameras. It shows a nest with three eggs plus an adult bird doing some site maintenance.

As usual, a dedicated team surveyed our butterflies in 2020. Butterfly numbers tend to peak in April and July but Covid-19 restrictions meant that the April peak was entirely missed this year. Nevertheless counts were conducted thereafter and these suggest that overall 2020 was a slightly below average year for butterflies.

This year's two lockdowns have changed for the better many people's perspectives on nature and nature reserves, as illustrated by this recent article from the Watford Observer.

 November 2020

Covid-19 restrictions unfortunately led to cancellaton of this year's public Butterfly and Dragonfly Walk (amongst others) but FoSL members, father and son Rob and Alex Liddle, agreed to report back on a private walk around the lake. You can read their report here or else download an illustrated version from here.

August 2020 

In common with so many other public events, our wildflower walk around the lake which had been scheduled for June 21st unfortunately had to be cancelled due to Covid-19. However on July 1st Janet Lowndes and Linda Ascroft walked around the lake and listed the various wildflowers they identified.
